為讓本發明之上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the present invention will be more apparent from the following description.
圖1為本發明第一實施例之光電模組的立體示意圖。圖2為對應圖1之剖線A-A’所繪之剖面圖。請參照圖1及圖2，本實施例之光電模組100包括基板110、至少一光電元件120、至少一導光元件130以及至少一菲涅耳透鏡132(Fresnel lens)。圖1所示之光電模組100繪出二個光電元件120、十二個導光元件130及十二個菲涅耳透鏡132做為代表。然而，本發明並不特別限定光電元件120、導光元件130及菲涅耳透鏡132的數量。光電元件120、導光元件130及菲涅耳透鏡132的數量皆可視實際的需求做適當之設計。1 is a perspective view of a photovoltaic module according to a first embodiment of the present invention. Figure 2 is a cross-sectional view taken along line A-A' of Figure 1. 1 and 2, the photovoltaic module 100 of the present embodiment includes a substrate 110, at least one photovoltaic element 120, at least one light guiding element 130, and at least one Fresnel lens 132. The photovoltaic module 100 shown in FIG. 1 depicts two photovoltaic elements 120, twelve light guiding elements 130, and twelve Fresnel lenses 132 as representative. However, the present invention does not particularly limit the number of the photovoltaic element 120, the light guiding element 130, and the Fresnel lens 132. The number of the photovoltaic element 120, the light guiding element 130 and the Fresnel lens 132 can be appropriately designed according to actual needs.
本實施例之基板110具有承載面110a以及與承載面110a連接且相對於承載面110a傾斜之反射面110b。更進一步地說，本實施例之基板110更具有相對於承載面110a之底面110c、連接底面110c與承載面110a之周面110d、以及連接周面110d與反射面110b之頂面110e。在本實施例中，承載面110a與反射面110b可夾鈍角θ。鈍角θ之角度可依實際的需求做適當之調整。在本實施例中，鈍角θ之精度可視半導體製程蝕刻精度而定。舉例而言，鈍角θ之角度可為135度。本實施例之基板110可為半導體基板，例如矽基板。但，本發明不以上述為限。The substrate 110 of the present embodiment has a bearing surface 110a and a reflecting surface 110b connected to the bearing surface 110a and inclined with respect to the bearing surface 110a. Furthermore, the substrate 110 of the present embodiment further has a bottom surface 110c with respect to the bearing surface 110a, a peripheral surface 110d connecting the bottom surface 110c and the bearing surface 110a, and a top surface 110e connecting the circumferential surface 110d and the reflecting surface 110b. In this embodiment, the bearing surface 110a and the reflecting surface 110b may have an obtuse angle θ. The angle of the obtuse angle θ can be appropriately adjusted according to actual needs. In the present embodiment, the accuracy of the obtuse angle θ may depend on the etching precision of the semiconductor process. For example, the angle of the obtuse angle θ can be 135 degrees. The substrate 110 of this embodiment may be a semiconductor substrate such as a germanium substrate. However, the invention is not limited to the above.
本實施之光電元件120與基板110連接且面向基板110之反射面110b。更清楚地說，光電元件120可具有工作面120a(繪於圖2)。工作面120a朝向承載面110a及反射面110b。在本實施例中，光電元件120可直接地與基板110接合。更進一步地說，光電元件120可利用覆晶(flip-chip)方式裝設(mount)於基板110之頂面110e上。如圖2所示，本實施例之光電元件120適於提供或接收光訊號L。換言之，光電元件120可為發光元件或光檢測元件。更進一步地說，光電元件120a可為發光元件，而光電元件120b可為光檢測元件。在本實施例中，發光元件可為雷射或其他合適的發光元件，其中雷射可為垂直共振腔面射雷射(vertical cavity surface emitting laser，VCSEL)。光檢測元件例如為光二極體(photo-diode，PD)。但，本發明不以上述為限。The photovoltaic element 120 of the present embodiment is connected to the substrate 110 and faces the reflective surface 110b of the substrate 110. More specifically, the photovoltaic element 120 can have a working surface 120a (shown in Figure 2). The working surface 120a faces the bearing surface 110a and the reflecting surface 110b. In the present embodiment, the photovoltaic element 120 can be directly bonded to the substrate 110. Furthermore, the photovoltaic element 120 can be mounted on the top surface 110e of the substrate 110 by a flip-chip method. As shown in FIG. 2, the photovoltaic element 120 of the present embodiment is adapted to provide or receive an optical signal L. In other words, the photovoltaic element 120 can be a light emitting element or a light detecting element. Further, the photovoltaic element 120a may be a light emitting element, and the photovoltaic element 120b may be a light detecting element. In this embodiment, the illuminating element may be a laser or other suitable illuminating element, wherein the laser may be a vertical cavity surface emitting laser (VCSEL). The photodetecting element is, for example, a photo-diode (PD). However, the invention is not limited to the above.
請再參照圖1及圖2，本實施例之導光元件130位於基板110之承載面110a以及光訊號L之傳遞路徑上。在本實施例中，導光元件130可為凸起於承載面110a之凸條。此凸條可覆蓋基板之反射面110b且朝向遠離反射面110b的方向延伸。導光元件130之材質的選用，以導光元件130之折射率為首要的考量。詳言之，為使光訊號L可在導光元件130中發生全反射而順利地傳遞，導光元件130之折射率可大於環境介質(例如空氣)之折射率。舉例而言，導光元件130可為光波導，其材質可為聚合物(polymer)、矽、氧化矽或其他介電材料。另外，本實施例之導光元件130可利用半導體製程製作。然而，本發明不限於此，在其他實施例中，導光元件130亦可利用塗佈、印刷等方式製作。Referring to FIG. 1 and FIG. 2 again, the light guiding component 130 of the present embodiment is located on the bearing surface 110a of the substrate 110 and the transmission path of the optical signal L. In this embodiment, the light guiding element 130 may be a ridge protruding from the bearing surface 110a. The ridges may cover the reflective surface 110b of the substrate and extend in a direction away from the reflective surface 110b. The selection of the material of the light guiding element 130 is based on the refractive index of the light guiding element 130. In detail, in order for the optical signal L to be smoothly transmitted by total reflection in the light guiding element 130, the refractive index of the light guiding element 130 may be greater than the refractive index of an environmental medium such as air. For example, the light guiding element 130 can be an optical waveguide, and the material thereof can be polymer, germanium, yttria or other dielectric materials. In addition, the light guiding element 130 of the present embodiment can be fabricated by a semiconductor process. However, the present invention is not limited thereto, and in other embodiments, the light guiding element 130 may be fabricated by coating, printing, or the like.
值得注意的是，菲涅耳透鏡132設置於導光元件130上與光訊號L之傳遞路徑上，並位於基板110之反射面110b與光電元件120之間。菲涅耳透鏡132可將光電元件120所發出之光訊號L聚焦至反射面110b上。換言之，透過菲涅耳透鏡132的聚焦作用，光電元件120所發出之光訊號L可有效地耦合至導光元件130中。耦合效率高(即能量高)之光訊號L可透過反射面110b之反射而在導光元件130中傳輸較長的距離。It should be noted that the Fresnel lens 132 is disposed on the light guiding element 130 and the transmission path of the optical signal L, and is located between the reflective surface 110b of the substrate 110 and the photoelectric element 120. The Fresnel lens 132 can focus the optical signal L emitted by the photocell 120 onto the reflective surface 110b. In other words, the optical signal L emitted by the photo-electric element 120 can be effectively coupled into the light guiding element 130 by the focusing action of the Fresnel lens 132. The optical signal L having high coupling efficiency (i.e., high energy) can transmit a long distance in the light guiding element 130 through the reflection of the reflecting surface 110b.
圖3為圖2所示之光電模組的局部放大圖。請參照圖3，在本實施例中，製造者可利用半導體製程在導光元件130上製作所述之菲涅耳透鏡132。由於菲涅耳透鏡之厚度可較一般之凸透鏡薄，因此本實施例之光電模組100還具有易薄型化之優點。3 is a partial enlarged view of the photovoltaic module shown in FIG. 2. Referring to FIG. 3, in the present embodiment, the manufacturer can fabricate the Fresnel lens 132 on the light guiding element 130 by using a semiconductor process. Since the thickness of the Fresnel lens can be thinner than that of a general convex lens, the photovoltaic module 100 of the present embodiment has the advantage of being easy to be thinned.
圖4、圖6為本發明第二實施例之光電模組的立體示意圖。圖5為對應圖4之剖線B-B’所繪之剖面圖。請參照圖4及圖5，本實施例之光電模組100A與第一實施例之光電模組100類似，因此相同之元件以相同之標號表示。本實施例之光電模組100A與第一實施例之光電模組100之差異在於：本實施例之導光元件130A與第一實施例之導光元件130不同。此外，如圖6所示，本實施例之光電模組100A更包括載板140及光學轉接頭150。以下就此差異處做說明，兩者相同之處便不再重述。4 and FIG. 6 are schematic perspective views of a photovoltaic module according to a second embodiment of the present invention. Fig. 5 is a cross-sectional view corresponding to the line B-B' of Fig. 4. Referring to FIG. 4 and FIG. 5, the photovoltaic module 100A of the present embodiment is similar to the photovoltaic module 100 of the first embodiment, and therefore the same components are denoted by the same reference numerals. The difference between the photovoltaic module 100A of the present embodiment and the photovoltaic module 100 of the first embodiment is that the light guiding element 130A of the present embodiment is different from the light guiding element 130 of the first embodiment. In addition, as shown in FIG. 6 , the photovoltaic module 100A of the embodiment further includes a carrier 140 and an optical adapter 150 . The following is a description of this difference, and the similarities between the two will not be repeated.
請參照圖4及圖5，本實施例之導光元件130A可為另一種形式的光波導結構，包括具有至少一凹槽134a之第一介質層134、覆蓋凹槽134a與第一介質層134之第二介質層136、以及位於第一介質層134與第二介質層136之間且填入凹槽134a之第三介質層138。第一介質層134之材料可為矽或氧化矽；第二介質層136之材料可為矽或氧化矽；第三介質層138之材料，可為聚合物、矽或氧化矽，依製程決定。菲涅耳透鏡132可形成在第二介質層136上。 在本實施例中，菲涅耳透鏡132可位於第三介質層138與光電元件120之間，其中第三介質層138適於傳遞光訊號L。Referring to FIG. 4 and FIG. 5 , the light guiding component 130A of the present embodiment may be another form of optical waveguide structure including a first dielectric layer 134 having at least one recess 134 a , a covering recess 134 a and a first dielectric layer 134 . A second dielectric layer 136, and a third dielectric layer 138 between the first dielectric layer 134 and the second dielectric layer 136 and filled with the recess 134a. The material of the first dielectric layer 134 may be tantalum or tantalum oxide; the material of the second dielectric layer 136 may be tantalum or tantalum oxide; the material of the third dielectric layer 138 may be polymer, tantalum or tantalum oxide, depending on the process. A Fresnel lens 132 can be formed on the second dielectric layer 136. In the present embodiment, the Fresnel lens 132 can be located between the third dielectric layer 138 and the photovoltaic element 120, wherein the third dielectric layer 138 is adapted to transmit the optical signal L.
如圖5所示，光電元件120所發出之光訊號L穿過菲涅耳透鏡132後可依序經過第二介質層136、第三介質層138而匯聚至反射面110b上。透過菲涅耳透鏡132的聚焦作用，光電元件120所發出之光訊號L可有效地耦合至導光元件130A中，進而在第三介質層138中傳遞。換言之，藉由菲涅耳透鏡132，本實施例之光電模組100A的光耦合效率可提高。As shown in FIG. 5, the optical signal L emitted by the photoelectric element 120 passes through the Fresnel lens 132 and then converges through the second dielectric layer 136 and the third dielectric layer 138 to the reflective surface 110b. Through the focusing action of the Fresnel lens 132, the optical signal L emitted by the photo-electric element 120 can be effectively coupled into the light guiding element 130A and further transmitted in the third dielectric layer 138. In other words, with the Fresnel lens 132, the optical coupling efficiency of the photovoltaic module 100A of the present embodiment can be improved.
請參照圖6，本實施例之光電模組100A可選擇性地包括載板140以及光學轉接頭150。在本實施例中，光學轉接頭150可為一多芯連接器(MPO,Multi-Fibre Push-on或MTP,Multi-fiber Termination Push-on)或其他類型的光學轉接頭。基板110、光電元件120、導光元件130A以及光學轉接頭150可位於載板140之同一表面140a上。光學轉接頭150可位於導光元件130A旁以及光訊號(未繪示)之傳遞路徑上。光學轉接頭150可將導光元件130A所傳輸之光訊號轉接到其他導光元件中，而使本實施例之光電模組100A實現易插拔之功能。此外，本實施例之光電模組100A亦具有與第一實施例之光電模組100類似之功效及優點，於此便不再重述。Referring to FIG. 6 , the photovoltaic module 100A of the embodiment may optionally include a carrier 140 and an optical adapter 150 . In this embodiment, the optical adapter 150 can be a multi-fiber connector (MPO, Multi-Fibre Push-on or MTP, or other type of optical adapter). The substrate 110, the photovoltaic element 120, the light guiding element 130A, and the optical adapter 150 may be located on the same surface 140a of the carrier board 140. The optical adapter 150 can be located beside the light guiding element 130A and on the transmission path of the optical signal (not shown). The optical connector 150 can transfer the optical signal transmitted by the light guiding component 130A to other light guiding components, so that the photovoltaic module 100A of the embodiment can realize the function of being easy to insert and remove. In addition, the photovoltaic module 100A of the present embodiment also has similar functions and advantages as the photovoltaic module 100 of the first embodiment, and will not be repeated here.

Referring to FIG. 7, FIG. 8, and FIG. 9, the photovoltaic module 100B of the present embodiment is similar to the photovoltaic module 100A of the second embodiment, and therefore the same components are denoted by the same reference numerals. The photovoltaic module 100B of the present embodiment is different from the photovoltaic module 100A of the second embodiment in that the photovoltaic module 100B of the present embodiment further includes another light guiding component 160 and a positioning structure 170. The following is a description of this difference, and the similarities between the two will not be repeated.
如圖8所示，本實施例之光電模組100B可進一步包括至少一導光元件160。導光元件160位於光訊號之傳遞路徑上且導光元件160之一端與導光元件130A連接。詳言之，本實施例之導光元件160可為光纖。光纖可與導光元件130A之第三介質層138對準，而使原本在第三介質層138傳遞之光訊號可耦合至光纖中。As shown in FIG. 8 , the photovoltaic module 100B of the embodiment may further include at least one light guiding component 160 . The light guiding element 160 is located on the transmission path of the optical signal and one end of the light guiding element 160 is connected to the light guiding element 130A. In detail, the light guiding element 160 of the embodiment may be an optical fiber. The optical fiber can be aligned with the third dielectric layer 138 of the light guiding element 130A such that the optical signal originally transmitted at the third dielectric layer 138 can be coupled into the optical fiber.
另外，如圖7及圖8所示，為了固定導光元件160，本實施例之光電模組100B可進一步包括定位結構170。定位結構170設置於基板110上。定位結構170具有凹槽170a。凹槽170a可為V型溝槽(V-groove)。導光元件160可置入凹槽170a中，受凹槽170a侷限而定位在基板110上，進而確保導光元件130A與導光元件160之間的光耦合效率穩定。此外，如圖9所示，本實施例之光電模組100B亦可包括光學轉接頭180。光學轉接頭180可與導光元件160之另一端連接。透過光學轉接頭180，光電模組100B可將導光元件160所傳輸之光訊號轉接到其他導光元件中，而使本實施例之光電模組100B可實現易插拔之功能。In addition, as shown in FIG. 7 and FIG. 8 , in order to fix the light guiding component 160 , the photovoltaic module 100B of the embodiment may further include a positioning structure 170 .

綜上所述，本發明一實施例之光電模組可利用菲涅耳透鏡將光電元件所發出之光訊號聚焦至導光元件上中，進而提高光電模組的光耦合效率。此外，由於菲涅耳透鏡之厚度較薄，因此本發明一實施例之光電模組還具有易薄型化之優點。In summary, the photovoltaic module according to an embodiment of the present invention can use a Fresnel lens to focus the optical signal emitted by the photoelectric component onto the light guiding component, thereby improving the optical coupling efficiency of the photovoltaic module. In addition, since the thickness of the Fresnel lens is thin, the photovoltaic module according to an embodiment of the present invention has the advantage of being easy to be thinned.
